SPECIFICATION forming part of Letters Patent No. 624,133, dated May 2,1899. Application filed August 18,1898- Serial No. 688,895. (No model.)

an elevation of a tip embodying my invention. Fig. 2 is a topviewthereof. Fig. 3 is a vertical section. Fig. 4 is also a vertical sectionin a plane at right angles to the plane of Fig. 3.

Similar letters of reference refer to corresponding parts in all of thefigures.

A represents a tip of any desired material.

It is formed with a central and vertical cham her a at its top and witha horizontal air-passage a, extending diametrically across the tip andintersecting the vertical chamber a at its lower end.

a represents inclined air-passages arranged diametrically opposite eachother and intermediate the ends of the horizontal passage a.

B represents gas-passages arranged diametrically opposite each other inthe tip and extending from the bottom of the tip up- Wardly.

1) represents constricted and inclined passages leading from the upperends of the passages B to the vertical chamber a. Each of these passagesis parallel with an adjacent air-passage ad.

The operation of the tip seems to be: The gas issuing from theconstricted passages will meet to form a flat flame, which is carriedaway from the surface of the tip by the air drawn from the centralchamber a. The issuing gas also draws air through the inclined passagesa which keeps the outside of the flame cool and prevents any deposit ofcarbon at that point.

What I claim as my invention is- 1. A tip for burners formed with acentral chamber in its top, an air-passage extending diametricallythrough the tip and intersecting said chamber, vertical gas-passagesdiametrically opposite each other, and constricted inclined passagescommunicating at one of their ends with said vertical passages and attheir other ends with the central chamber above thediametrically-extending air-passage.

2. Atip for burners provided with a central chamber in its top, anair-passage extending diametrically through the tip and intersectingsaid chamber, inclined air-passages arranged diametrically opposite eachother, vertical gas-passages arranged diametrically opposite each other,and inclined gas-passages each parallel with an adjacent inclinedairpassage and communicating with an adjacent vertical gas-passage andthe central chamber.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JOSEPH A. VINCENT.
